When compiling from source revision 216942 acpiconf stops responding. I also tried to remove r216942 and compiled from source release 9.3, but there battery status was not working.

If true (in all cases) this is great news for those with a variety of HP laptops that have been experiencing partial - or in some cases complete after boot - failures in CMBAT monitoring since 9.0. And a Macbook Pro. So, reverting rev 216942 fixes it for you? On what FreeBSD version? If so, with scant comprehension of the code, questions that occur: a) did that revision fix some existing problem, the reverting of which might reestablish problem/s in other machines? jkim? b) what is it in various HP ACPI implementations that don't seem to be a reported problem on other hardware, particularly concerning EC handling? c) if this was wrong (for HPs), what would be right? (the hard one :) cheers, Ian
